The hemipenis is the intromittent organ of Squamata, [4] which is the second largest order of vertebrates with over 9,000 species distributed around the world. They differ from the intromittent organs of most other amniotes such as mammals, archosaurs and turtles that have a single genital tubercle, as squamates have the paired genitalia remaining separate. [5]
The eggs are usually laid in dark and humid areas. They are rarely laid on the snake where the adult mites are found. Eggs hatch in one day in ideal conditions. After hatching, the young mites go through the larval stage, which takes about one or two days. The larvae tend to move very little away from the eggs, despite having the ability to walk.
The eggs of the egg-laying mammals (the platypus and the echidnas) are macrolecithal eggs very much like those of reptiles. The eggs of marsupials are likewise macrolecithal, but rather small, and develop inside the body of the female, but do not form a placenta.
Dasypeltis scabra feeds exclusively on eggs. The lining of the mouth has small, parallel ridges, very similar to human fingerprints, which aid in grasping the shell of an egg. Once swallowed, the egg is punctured by specialized vertebral hypapophyses which extend into the esophagus.
Egg protection on dry land. [23] While oviparous animals either have a jelly like ovum or a hard shell enclosing their egg, internally fertilizing animals grow their eggs and offspring inside themselves. This offers protection from predators and from dehydration on land. [24]

For example, the African egg-eating snake has flexible jaws adapted for eating eggs much larger than the diameter of its head. [26]: 81 This snake has no teeth, but does have bony protrusions on the inside edge of its spine, which it uses to break the shell when eating eggs. [26]: 81
It was when the 13-foot, 9-inch snake lunged to bite that he got a grip on her head and pulled the snake from the nest. Multiple egg “squirted out” during the capture, the video shows.
